Except one of the reasons as to why No Mans Sky became such a huge failure is because Sony among others rushed the developers to release it, not giving them time to fulfill almost any of the promises they'd made on the game. Resulted in Sony eventually pulling out entirely from the game because it became such a failure due to being so rushed. Ironic.

We are not 100% sure that was the true reason, it could have been but also couldn't. Still, the game was under development for several years and it was delayed so many times.
